Diagnostic readout help
Saturday, March 15, 2014 4:56 PM
So I hooked my car up to a diagnostic to see what was going on with it because its been acting funky.
At idle I have 9.4 % tps reading
30% load
Idle is at 950
Intake air temp is 104
Vacuum is at 20.8
And timing is at 13.5

At full throttle I'm getting 86% tps reading
100%load
AIT is 204
And Only 9lbs boost with 3in pulley

It's running rich as crap at full throttle but sounds like a 2 stroke.
I'm thinking vacuum leak.

Any inside would be loved

at full throttle it is richer than 10:1

What im really trying to figure out is why its at 30% load at idle
Why the tps reads 9.4% at idle
Why it sounds like its running lean at full throttle when the afr's are rich

Incase anyone is reading this the issue was a huge intake gasket leak
